Product details

Wolt 18 L hydration backpack with 2 L bladder – light grey

After something compact and no-nonsense that just gets the job done? The Stormer Wolt 18 L hydration backpack is built for days when speed and simplicity matter. It gives you a neat 18 litres of storage and comes with a 2 L leakproof bladder, so you can sip on the move without faffing about.

Key features

  • The main compartment swallows layers, snacks and a small repair kit, while two front pockets keep bits you need quick access to — phone, keys or a map — within easy reach.
  • A dedicated helmet holder and utility loops keep cycle kit or climbing gloves tucked away and out of the way when you don’t need them.
  • Water-resistant polyester plus a stowable rain cover protects your kit in a sudden downpour — handy on mixed-weather days.
  • Breathable, padded back and shoulder straps help cut down on sweat on longer outings, and the adjustable chest and waist straps keep the load stable when you’re moving fast.
  • The included 2 L bladder is leakproof and straightforward to fill and clean — no awkward maintenance to worry about.

why it’s useful

Perfect for day hikes, fastpacking, cycle commutes or gym runs where a bulky rucksack would be overkill. It keeps essentials tidy and easy to reach, and the hydration system means your hands stay free. There’s a reflective strip for better visibility on early starts or late finishes, and a whistle on the stabiliser strap for added peace of mind if you’re out on quieter trails.

technical details and care

  • Capacity: 18 L, with a 2 L bladder included.
  • Approximate dimensions: 14 x 28 x 47 cm — sits close to the back so it won’t flap about.
  • Material: polyester with a water-resistant treatment; includes a separate rain cover for heavier showers.
  • Weight: not specified on the label — designed to be lightweight and compact for active use.
  • Bladder care: rinse after each use, leave to air dry completely (cap off) before storing to avoid lingering odours.

common questions

Will it fit a laptop? No — this is a daypack made for activity, not for lugging tech. Is the bladder insulated? No, it’s a standard 2 L bladder; pop it in an insulated sleeve if you want to keep drinks cooler on hot days. Can it be used for cycling? Yes — the stabiliser strap and helmet holder make it handy for both road and off‑road rides.

All in all, this is a straightforward, reliable hydration pack for anyone who wants light, ready‑to‑go performance on the trail without any faff. If the aim is quick, simple and dependable, this does the trick.
